Abstract (en)

Systems and methods for integrating emulated and native code are provided. One embodiment comprises a method for emulating code from an original computer system on a host computer system. Briefly described, one such embodiment comprises the steps of: fetching (200) a program instruction associated with program code to be emulated on a host computer system; determining (202) whether the program instruction is to be executed natively on the host computer system or is to be emulated on the host computer system; and if the program instruction is to be executed natively on the host computer system, emitting (206) a native code fragment associated with the program instruction into a dynamic execution layer interface (104) to be executed. <IMAGE>
